No way to construct mixed dtype DataFrame without total copy, proposed solution · Issue #9216 · pandas-dev/pandas
After hours of tearing my hair, I've come to the conclusion that it is impossible to create a mixed dtype DataFrame without copying all of its data in. That is, no matter what you do, if you want to create a mixed dtype DataFrame, you will inevitably create a temporary version of the data (e.g. using np.empty), and the various DataFrame will constructors will always make copies of this temporary.
